Paul Krugman on Milton Friedman

From the New York Review of Books:

Screenhunter_02_jan_26_1636 Keynesianism was a great reformation of economic thought. It was followed, inevitably, by a counter-reformation. A number of economists played important roles in the great revival of classical economics between 1950 and 2000, but none was as influential as Milton Friedman. If Keynes was Luther, Friedman was Ignatius of Loyola, founder of the Jesuits. And like the Jesuits, Friedman’s followers have acted as a sort of disciplined army of the faithful, spearheading a broad, but incomplete, rollback of Keynesian heresy. By the century’s end, classical economics had regained much though by no means all of its former dominion, and Friedman deserves much of the credit.

I don’t want to push the religious analogy too far. Economic theory at least aspires to be science, not theology; it is concerned with earth, not heaven. Keynesian theory initially prevailed because it did a far better job than classical orthodoxy of making sense of the world around us, and Friedman’s critique of Keynes became so influential largely because he correctly identified Keynesianism’s weak points. And just to be clear: although this essay argues that Friedman was wrong on some issues, and sometimes seemed less than honest with his readers, I regard him as a great economist and a great man.
